When it's time to replace your roof, the quantity of information offered can be frustrating. Lots of websites and videos enter into fantastic information on how to shingle a roof. This post from the professionals at IKO Roof will assist you understand everything by highlighting the basic steps and detailing the fundamental purpose for each roofing system element.
The next time you check out the plan guidelines or watch a how-to video on YouTube, you'll have a much better understanding of why roofing system shingles are installed the method they are. Operating at heights on a roofing system provides fall hazard threats and other safety concerns. IKO recommends that roof work be done by qualified specialists who understand the very best way to shingle a roofing system and have actually been totally trained in all elements of roofing system building security.
Asphalt roofing shingles just depend on the force of gravity to shed water from rain or snow melt. If the roof shingles and all accessory roofing parts are arranged and overlapped with this in mind, the roofing must effectively shed water. In the dictionary, "to shingle" is defined as "to set out or arrange so as to overlap." So now let's take a look at the series of overlapping roofing system building parts to see how this uses.
Having a tidy, flat deck surface will help make sure that the recently shingled roof will likewise appear smooth and flat when finished. Not just are we working from the bottom of the roofing system, we're likewise starting with the bottom-most layer, in terms of roofing parts - installing shingles. The asphalt roofing system shingles are the noticeable part and the first line of defense versus harsh weather condition, however what's beneath them actually counts.
It actually provides a clean, sharp edge for the start of the roofing and protects the lower edge of the roof deck from water damage by preventing water from "defying gravity" and wicking back "up" prior to it leaves the roofing. Drip edge is installed under the ice and water at the eaves and on top of the ice and water and underlayment on the rakes.
This thin, self-adhering membrane is the next element and it gets installed over the drip edge. Ice dam formation is finest prevented by having an appropriate attic vapor barrier, adequate attic insulation and comprehensive ventilation; however, an ice protection membrane is a sensible roof element and is likely needed by your regional building code in cold climates.
To be fully efficient, it must extend up the roofing system to a point a minimum of 24 inside the vertical extension of the interior side of the wall. At this time, any valleys on the roofing ought to likewise be flashed with an ice and water membrane. Why an ice and water protector? Due to the fact that these membranes work on the concept that their rubberized asphalt finishing seals around the shanks of the overlying shingle fasteners, including an extra degree of water-shedding security.
Both use you peace-of-mind protection underneath the shingles. While the asphalt shingles will be the main water-shedding roofing system layer, there are many benefits to setting up a roof underlayment. The felt is laid in horizontal courses, overlapping the eave ice and water protector by 4 and the valley membrane flashing by 6.
Keep in mind that drip edge we installed at the bottom of the roof? When going up the sloped edges of the roofing system (called the "rakes") it goes on top of the underlayment. Although this seems to contradict the overlapping principle, installing the drip edge over the underlayment at the rakes produces a clean roofing system edge and supplies the underlayment accessory with increased resistance against wind uplift.
IKO's RoofGard-Cool Grey Synthetic Roofing Underlayment offers your roofing secondary layer of protection. installing shingles. If a roofing is going to leakage, it will probably happen any place the shingle layer is penetrated, disrupted or satisfies a wall. These are the unique areas that require flashing an added layer of water-shedding product to assist keep the water running downslope.
If your roofing will have open valleys, which IKO advises, now is when the valleys must be lined with a pre-formed width of corrosion-resistant metal. Closed valleys are completed throughout shingle setup. For longer roof performance, IKO highly advises open metal valleys. Complete the application of underlayment and valley flashing before the roof shingles are applied.
Center a 914 mm (36) width strip of an ice and water protector membrane in the valley. The product is tacked in location briefly along one edge. Carefully peel away the backing, and put it in place, smoothing out any wrinkles. Start working from the eave, permitting additional pieces to overlap by at least 150 mm (6 ).
